I have an AWS EMR cluster which has Ganglia. However, I won't have access to any of the metrics once the cluster terminates. My understanding is that Ganglia's web interface depends on the RRD files stored (in my case) at
/var/lib/ganglia/rrds. I've exported these files - is there any way to set up Ganglia's web interface so that I can view them again?
I tried setting up a Docker image containing the web interface, and mounting the RRD files there. After changing the permissions, this successfully got the web interface running, but there is no data in the UI. It seems like gmetad expects to be able to connect to gmond processes, but I just want it (or the web interface, I don't really understand which parts are which) to serve data from RRDs only.
